Some features of Amazon’s eighth generation fulfillment center include:

Kiva robots of which Amazon currently has more than 15,000 operating across the U.S.;
Robo-Stow, one of Earth’s largest robotic arms moving large quantities of inventory for customer order fulfillment;
New vision systems enabling the unloading and receipt of an entire trailer of inventory in as little as 30 minutes instead of hours; and
New, high-end graphically oriented computer systems for employees to use while fulfilling orders for customers.
Amazon recently announced it will hire 80,000 seasonal employees to fulfill customer orders this holiday, a 14 percent increase over last year. The company expects that thousands of those employees will stay on in regular, full-time roles.
